Jekyll multiple post types

I'm currently building my new personal website and I'm trying out Jekyll, now I was wondering what the best way is to get multiple post types. I basically want to have 2 categories: blog and work I was looking up some ways and one way was to just create folders for each specific category ``` - work -- _posts --- portfolio01.md --- portfolio02.md - blog -- _posts --- blogitem01.md --- blogitem02.md ``` This way seems to work just fine. After checking if this was the correct solution I found another one, this basically suggested to use subfolders inside the `_posts` folder and then define a category in the post itself. ``` - _posts -- blog --- blogitem01.md --- blogitem02.md -- work --- portfolio01.md --- portfolio02.md ``` Both methods seem to have the exact same output, is there any real difference in this? Method one seems to be easier as you don't have to set a specific category inside each post.
